From 6ab8e6231f75500ea4d0c7755032ffc98e71a25f Mon Sep 17 00:00:00 2001 From: Chandler Carruth Date: Tue, 4 Oct 2011 21:22:42 +0000 Subject: [PATCH] Now that multiple prefixes are much cheaper to search for GCC installations, support them when installed directly under the system root ('/lib/gcc/...' essentially). With this, Clang can correctly detect and use a cross-compiling GCC installation within a system root and use it. Again, test cases will be coming in later commits, as I'm going to write a few test cases that exercise nearly all of this logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141121 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Driver/ToolChains.cpp | 1 + 1 file changed, 1 insertion(+) diff --git a/lib/Driver/ToolChains.cpp b/lib/Driver/ToolChains.cpp index ec11e73a18..14ac85ecb5 100644 --- a/lib/Driver/ToolChains.cpp +++ b/lib/Driver/ToolChains.cpp @@ -1639,6 +1639,7 @@ public: // Compute the set of prefixes for our search.
